The Abbott and Costello Show(1957)

Bud and Lou are unemployed actors living in Mr. Fields' boarding house. Lou's girlfriend Hillary lives across the hall. Any premise would lead to slapstick, puns, lots of gimmicks from their movies....

Barry Conrad, a nasty individual whose personality has richly endowed him with enemies, finally meets his end. Mason manages to see Jackson Sidemark acquitted - and then Sidemark dies. Did Winnifred Glover kill him? Both of them? Or was it someone else entirely?
